1-MCP
To an ethylene receptor, the 1-MCP molecule is similar to ethylene, but more attractive.

Ethylene Biosynthesis
Methionine
AVG
ACC
Inhibits production of the enzyme, ACC
synthase, which produces ACC - the rate
limiting step in the biosynthesis of ethylene

Inhibit ethylene perception by receptor sites
Physiological effects of ethylene
“Real time” because mode of action allows application close to harvest

How Does HarvistaTM and SmartFresh Technology Work?
• 1-MCP outcompetes ethylene for
receptor sites at the cellular level
and disables them.
• Since treated apples no longer
respond to ethylene, storage and
shelf life are preserved.
• It also inhibits storage scald.
|

How Does SmartFresh Technology Work?
• Eventually, fruit will produce
new ethylene receptor sites
• Restoring ethylene perception
and slowed ripening response.
• However, benefits continue
after storage removal.

Safety Profile
•  Highest regulatory safety class in
the U.S. and E.U.
•  Biodegrades in hours
•  No residual trace
•  Nontoxic
•  Ultra-low dosage: 1 part/million

Why is Harvista Important?
Buckeye Gala
•  Scatter plot of apple firmness
•  Application date: 8/21/15
•  Harvest 1 (H1): 9/3/15
•  Harvest 2 (H2): 9/10/15
•  Untreated apples become
increasingly variable with
harvest delays
>  Advanced apples are susceptible
to storage problems!
•  Harvista maintains firmness and
consistency!

•  Honeycrisp:
Conclusions
>  Coloring depends on grower cultural practices and weather
o  Application timing is very farm-dependent
o  No need to lower rates
o  Why? Results in less starch retention
o  Therefore, adjust application timing
o  60g rate applied around first week in September
o  Expect Extra-fancy coloring after 3 - 4 weeks
•  Fuji watercore mananagement, to be continued
Harvista
maintains
consistency!
